No VO2Max data

Former Member over 8 years ago

I'm still conversing with customer support on this, but I'm puzzled. I was hoping to track my VO2Max estimate.

My 230 has never shown any VO2Max data, even though it tracks my HR just fine. I'm using the chest strap that came with the watch.
I'm not in great shape but I'd still expect a VO2max number. I've had at least a dozen runs over 25 minutes outside with GPS on.

Most of this watch's features work well, although the buttons and menus could use improvement. Treadmill and GPS distance measurements are great.

I'm getting close to returning this device. Could there be a physiological reason why it isn't showing VO2max?

Thanks for any suggestions.

70 minutes

I went out yesterday for 70 minutes, and still no result.
Hopefully I'll understand more after a stress test that I'm working on scheduling.

I have a 235 and two weeks ago I ran a marathon in the trail so my pace was way lower than my road pace.
Interesting enough my VO2Max didn't get calculated and remained the same as it was before (49).
There was once when I did a training run of 10Kish in the mountain and that time it calculated but it was really low (because of the pacing).
So, it seems to me that these calculations happen when the stars are aligned. I don't know exactly which variables are involved at the same time so that it would happen.

Maybe you could try some steady runs of 1 hour or so?

Very strange... my 230 gave me my V02max after like 3 outdoor runs--none of them longer than 20 minutes. I'm using a Scosche Rhythm+ as my HRM. It's been changing every few months (flopping between 48 and 49) since I got the watch in December.

No VO2Max Data Solved!

I now know why my Forerunner 230 never calculated a VO2Max, and it's because I was in atrial fibrillation!

After undergoing a procedure to get my heart back into normal rhythm, my watch is calculating VO2Max after runs.
Of course, my resting and active hear rates are significantly different, too!

I *did* ask Garmin customer service if the "no VO2Max data" could be a physiological issue and they said "probably not", but - hey guess what? It was me, not the watch.

I recommend a stress test or other cardiac measurement for anyone who is seeing weird readings.

That's quite the outcome. I'm glad you are well now.

wow. thats a wild ending. Im having a similar issue. went on 3 runs so far. first two nothing. Garmin advised me on how to reset the monitor. I did. I've done another run since then, still nothing.

I was hoping maybe it takes a couple runs to acquire the data, or should have I seen one by the first run?

my runs are all at very decent paces, in fact because of the heat I'm running in (and mask) my zones are majority four and some good chunk five. theyre an avg of 25 min runs.
